  Update Information

A security update is available for thunderbird for the following
versions of Cucumber Linux:

Here are the details from the Cucumber 1.0 changelog:

+----------------+
Fri Oct 6 22:11:17 EDT 2017
xapps-general/thunderbird upgraded from 52.3 to 52.4. This most likely fixes
	some security issues, but Mozilla doesn't like to tell us about these
	until a couple of weeks after they publish the update (thanks guys). To
	be safe, we will treat this update as a security update.
